TOY VEH l CLE Filed May 21, 1937 'l UNITI-:lo STAT PATENT? Y l i i 'rox vautour matelots :ma willy keum, Nmobm, Germany :fsaia Glutn asuman-i to nia neuerv Appuesuon'msy 21, 1937, sensi Nia-144,083 In Germany November l1. 1935 s claims, 11.- 4s111) This invention relates to toy vehicles and more Y especially to toy vehicles operated by means of ai spring-driven clockwork which. in addition to .furnishing the driving power, is utilized to operate a device for producing operating noises, signals or similar sounds.A

Our invention essentially consists in a special and advantageous. novel construction 'of the aforesaid -sound producing device, said construc- 1`0 tion comprising an axle to which rotation as well as periodical swinging motion is impartedlby said clockwork, anda clapper mounted on said axle, said clapper coming Periodically in contact with the casing of the toy-vehicle to produce the de- 15 slrd operating noises, signals or similar sounds.

25 proper., In this manner, special sound produc-4 lng surfaces may be dispensed with, as the hollow casing of the toy-vehicle will itself` form the sounding member. Besides, our novel soundproducing device will require solely-an'additional axle which may easily be operatively connected with theclockwork and merely be provided with. a clapper adapted to come periodically linto ,sliding contact with said casing. Thus, by our present construction any further sound producing ,Y member will' be dispensed withv and, in addition,

said axle may be easily and conveniently assembled with the'clockwork during manufacture. Inthe accompanying drawing we have represented two forms of construction of our novel toyg vehicle and 4more particularly of our novel sound )Producing device. i f

The iii-st form of construction which comprises the aforesaid axle and clapper and control means inthe form of a ,cam and a tension spring for imparting, in addition to the. rotary motion, a

periodical swinging motion to said axle, is shown -in Figs. 1 and 3, 4 and 5.

Fig. 43 is a viewsimilar to Fig.' 1 of a modified form ofthe invention with the sounding means -in Fig. 4 is a view similar to Fig. 8 with the sound-f ing means in the-sounding position; and j r Fig. 5 is a plan view oi the device of Fig. 3 with parts broken away to disclose the operating' means., y Referring'more particularly to the several iigures of the drawing, acc'ordlng to Figs. 1 and 2 1b the rear axle together. with the rear-wheels of the toy-vehicle is driven by the intermediaryv of a gear-wheel or pinion l'and `the further gearwheel 3ffrom the main driving wheel l of the V clockwork whichais mounted within the casing'lg 4 of4 the` toy-vehicle. The gear-wheell 3 further serves to drive the .axleb by way of a pinion' 4 at one end of said axle, the other end of this axle carrying a crown-wheel 6 which is positioned at the outside of the casingZl for the clockwork and in mesh with a small gear-wheel or pinion l, the latter being mounted on the axle 8 which is directed longitudinally with respect. to the vehicle, said latter axle being provided atits front end with a toothed wheel 9 or clapper similar to a crown-wheel. The axle 8 is mounted within a bearing-nap zo on the casing 2| of the c1ock a f work only at the rear end thereof vto permit swinging of the axle 8 in a vertical plane. The axle 8 is also suspended byvmeans of a spring -III froma bracket ll fast on'the work. f

The axle 8 furthermorelisundercontrol of a cam I2 mounted on the winding stem oi'V the clockwork, said cam imparting downward swing-s 35 ing motion to said axle 8 against the actio 'of thespring l0 but periodically permitting thelatter to swing the axle 8 upwardly/with the eif'ect. that said toothed wheel or clapper Swill periodically lbeiressed against the casing on the toy V40 'andy again be retracted therefrom s o that said toothed wheel or clapper 9` upon contacting with Wall of said casing willproduce a sound imita g'that-of an ai'xatomobilefhorn.v

In order to more roperly generate. this sound, 45

.thecasing of the toy may beprovided at a place so' casing 2lv o f the clockclapper 9 comes periodically into sliding contact for producing said sound.

The second form of construction of our new toy-vehicle represented in Figs. 3, 4 and 5 comprises a spring-driven clockwork I mounted on the base-plate I5 of the toy-vehicle, said clock# work having its winding-stem at I' and serving for driving the axle 2 for the rear-wheels 3. One of the gear-wheels of the clockwork I further serves for driving an axle 5 by way of a pinion 4 at one end thereof, the other or outer end of said axle 5 carrying the crown-wheel 6 meshing with the pinion 'I on the axle 8' which is posi- ,tioned laterally of the clockwork and in longitudinal direction of the toy-vehicle. The front end of said axle 8' carries the toothed wheel or clapper 9' having .the form of a crown-wheel. At its rear end said axle 8 is mounted somewhat loosely in a bearing I3 which is preferably formed by a flap bent out of the casing of the clockwork. Said axle 8', in addition, is guided at a point nearer to its front end in a slotted bearing II' permitting upward and downward swinging of said axle. OnA the winding stem I of said lclockwork there is mounted the cam` I2' which upon operation of said clockwork will impart downward swinging motion to said axle 8 and the clapper 9 mounted thereon.

Engagement between the crown-wheel 6 and the pinion l on the axle 8' is such that rotation and periodical upward and downward swinging motion is imparted to said axle 8' and the clapp'er 9' thereon. In this case the casing I l of the toy may likewise be provided at the place of contact with said clapper 9' with corrugations, ribs, notches or the like as indicated at I3.

Upon rotation of the crown-wheel 6 said axle 8 and therewith said clapper 9' will be swung upward and moved into slight contact with the casing Il and the corrugations or the like at I3 thus producing the desired sound. The crown wheel 6 rotates in the direction of the arrow and rotates the pinion and the axle 8. Under the influence of this rotation, the loosely mounted axle 8 is, of course, vibrated and as the bottom and sides of the guide II prevent downward or lateral movement, it is swung upwards on its pivot I3' until further upward movement is prevented by the clapper 9' contacting the corrugation I3. This sound may further be improved by providing said clapper 9 on the axle 8 with an eccentical weight I' which by action of its centrifugal force will periodically-increase the contact or lsliding pressure between said clapper 9 and said casing I 4. While the upward swinging motion of said axle 8 and therewith the contact of said clapper 9' with said casing is effected by the rotation of said crown-wheel 6, the downward swinging motion of said axle 8 and said clapper 9 vis brought about by the cam I2 with the eiect of temporarily or periodically interrupting the produced sound.

The casing I l which covers up the clockwork I is mounted preferably loosely or with the intermediary of a sound insulating layer on the baseplate I of the toy-vehicle. The casing I4 thus will act practically as the sounding member of a bell thus improving the resonance of the sound produced during the sliding contact between clap- .per 9 and casing I I.

While we have shown and described herein a rotating axle 8 and clapper 9, which in addition to its rotation may be swung upward and downward in a vertical plane, it will also be possible to cause swinging of said axle and clapper in another plane, for instance in a horizontal plane.

We claim:
